Here's a start with Osiris's ownership chart for CCA

Wellington is a financial company.
Bill Ackman (of Pershing Square) is "the investing world's version of Elvis."

We're going to need a business librarian or someone with more business research expertise to take this question further.

This is a good question. Thanks for the link to the bailout visualization. I don't think you can make a one-to-one correlation between the bailouts in history and data on GDP and/or employment because there are so many factors that go into those data. Be that as it may, the US Department of Labor's Bureau of Labor Statistics is a good place to start for (un)employment statistics. GDP can be found at US Department of Commerce's Bureau of Economic Analysis. I believe you can also find those data in the US Statistical Abstract, available online and at your nearest Federal Depository Library.

I'm not sure how far back those data are available on their sites, so you may want to visit your local library. NY Public, as well as several University libraries in NYC should be able to help you if the data are not online. Here's a hint, any library that is a Federal Depository (like NYU) has to allow the public in to use Federal government information. So, you should be able to gain entrance to, for example, NYU, even though they're a private university.

Another angle to try is the secondary literature. That is, you can search in books to see if anyone has been able to make the correlation you're seeking. I searched Worldcat for "bailout" and found 287 books, many of which will get at your question. Once you find a book in which you're interested, you can put in your zip code and find the nearest library that has the title.
